Question

DATE:
area
@ The radius of a ciecle is 28 cm Find its area
​

Answer 1

Answer:

Area = 2468 sq. cm

Step-by-step explanation:

$area \: = \: \pi {r}^{2}$

r = 28 cm

by substituting in formula

Area = π × (28)^2

if π is taken as 22/7 then,

Area = (22 / 7) × 28 ×28

= 22×4×28 sq. cm

2468 sq. cm

or if π is taken as 3.14 then,

Area = 3.14 × 28 ×28

= 2461.78 sq. cm
